Acoustic neurinoma
Acoustic Neurinoma
Acoustic neurinoma, also known as vestibular schwannoma, is a benign, usually slow-growing tumor that develops on the main (vestibular) nerve leading from your inner ear to your brain.
Pronunciation
Acoustic neurinoma: /əˈkuːstɪk nʊərɪˈnoʊmə/
Etymology
The term "acoustic" is derived from the Greek word "akoustikos", which means "of or for hearing". "Neurinoma" comes from "neurin", a term for the sheath of a nerve, and "-oma", a suffix used in pathological terms to denote a tumor.
Symptoms
Symptoms of an acoustic neurinoma may include hearing loss, tinnitus (ringing in the ear), and dizziness. As the tumor grows, it may also cause facial numbness or weakness, balance problems, and headaches.
Causes
The exact cause of acoustic neurinoma is unknown. However, it is often associated with a genetic disorder known as neurofibromatosis type II (NF2).
Diagnosis
Diagnosis of acoustic neurinoma typically involves a hearing test, MRI (magnetic resonance imaging), and sometimes a CT scan (computed tomography).
Treatment
Treatment options for acoustic neurinoma include observation, surgery, and radiation therapy.
